Description
This unit describes the skills and knowledge required to design and specify appropriate testing and commissioning procedures while under industrial conditions in the field for polyethylene (PE) plastic pressure pipelines. This unit applies to an operator working alone or as part of a team.The unit principally refers to experienced operators who are required to select materials, components and designs for pressure applications of plastic pipelines to requirements, and specify appropriate testing and commissioning with high pressure water.No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
